What is mari-culture?
Mari-culture is the offshore
cultivation of marine organisms
A basic condition is the
natural settlement or spreading spawn to anthropogenic structures like
oil-stations or wind-energy bracket structures
No additional feeding
and no hygiene measures are necessary because a wind-park is open to all sides
Food intake and excrementation underlying natural conditions
Who can be cultivated?
The following species are of economic and
ecological interest in the southern North Sea:
Macro-algae:
Laminaria and Palmaria
useable in aliment, textile and color industry also in cosmetic and
pharmacological industry
Blue
Mussel/Mytilus edule: as
aliment
Oyster/Ostrea gigas: as aliment
Spongae: useable
in pharmacological industry
Lobster/Homarus vulgaris: resettlement of strongly reduced
population
In
other regions of the world other species can be cultivated
How can the system work?
The foundations of the offshore wind turbines
should accomplish the circumstances for a co-using of mari-culture
without confinement as a bracket for the turbines
Why offshore mari-culture?
Contrary to the
high-technology land based aquaculture, which produces only some few noble
fishes in completely aseptic conditions, mari-culture
can produce a high amount of bio-mass in natural way for different application
This is especial
interesting for transition nations/developing countries
The cost can be reduced
for both, the wind-park-owner and the mari-culture
operator: a classical „Win-Win“ situation
Which risk can be appear?
The risk
are the same as for other offshore constructions. Extreme wind and wave
action can destroy the structure.
The settlement and the
food supply underlie the natural conditions and can not
be controlled.
The accessibility is not given at any time, because the weather conditions in the North Sea are incalculable
